Use these fields to search for single lots with specific catalogue numbers.

With both start and end values: All lots in the interval are found (40
& 49 returns lots between 40-49)
Start value only: Lots with this catalogue number are found (2 & empty gives SM 2, SMF 2, etc.)
End value only: All lots up to this number are found (empty & 6 gives lots with cat.number 1-6)

Note! This function makes no difference between different catalogues, but looks for the number only.
